Hi Carl,

You will be safe if you fasten the panels to a healthy plywood 
sheathing. Unisolar panels are only as strong as the support structure, 
and the metal that the modules are glued to, even though they do add a 
certain amount of strength by virtue of their own materials. If you are 
in a high wind area and don't plan on using plywood sheathing, you 
should protect the underside of the structure so that the panels won't 
be blown off from the pressure. I would suggest using more clips if 
possible, and more purlins.
